Part 1.] identify the transformations that describe the graph of an odd function. select all that apply. reflection over the x-axis; reflection over the y-axis; reflection over the line y = x; 90° rotation around the origin; 180° rotation around the originpart 2.]  prove that if  f(x)  and  g(x)  are both even functions, then  h(x)  =  f(x)  +  g(x)  is an even function.
